变压器侧出线的短网参数

Parameters of heavy current lines concerning the side lead-out structure of transformer

通过对变压器采用顶出线和侧出线两种结构的短网参数计算比较,得到变压器侧出线结构可使短网电抗减小,电抗不平衡系数降低,从而降低电耗,提高三相电弧功率均衡和功率因数。

Parameters of heavy current lines are respectively calculated in respect to top lead-out and side lead-out of the transfor mer. Comparing the two calculating results, it is obtained that the side lead-out structure of transformer can make the reactances of the heavy current lines and their unbalance coefficient be reduced and then electric energy consumption decreased and the power balance and power factor of the arc furnace improved.
